Between the time I last used Poser and when I started noticing the error, there was a huge Windows 10 update (and several small ones). At the moment I am upgraded to the latest windows updates in my PC.I also installed MS Visual Studio 2017 and the Unity UI.Other than that, there were no new installations of note. No new poser plugins for a good while.

Doesn't seem to be. I set Reality.exe to run as administrator and double-clicked on the executable even outside of Poser (to see if I could at least bring up the interface), but I get the following error:

"The application was unable to start correctly (0xc0000142)"

Which, in my experience, is due to a mismatch of 32 and 64 bit libraries in the installed folder. However, I ran dependency walker through all pyc, exe and dll files in the folder and they are all 64 bits.

I also tried removing file by file from the reality installation folder. Obviously Reality would not start up correctly if I did that, but I hoped to find ONE file without which I could start Poser. If I remove "Reality_services.pyc", poser 64 does start up. If I remove some other file (for instance, ReGUID.pyc), I still get the warning of "Could not load the Reality plugin".

I also ran Reality with the Dependency walker profiler to see if I could come up with anything new. The profiler log is attached. You can see the error occurs while calling CreateDXGIFactory within c:\windows\system32\DXGIDEBUG.DLL, but I don't know what to do with this info.
